Light waves, like all electromagnetic waves, travel without a medium, so they can travel through empty space. Sound waves, on the other hand, do require a medium to travel or propagate; therefore, they can not travel through empty space.

Well light is an electromagnetic wave and it pushes itself through space ,but sound requires particles to travel through and if there are no particles for it to travel through you have no sound


sound cannot travel through empty space.


Sound waves cannot travel through empty space because they require air particles to transfer them. UV is a light wavelength and can travel through space (just like light from the Sun reaches the planets).


Sound waves cannot travel through an empty space because an empty space is usually a vacuum.


light can travel through a vacuum whereas sound cant


Both light and sound can indeed travel through glass. These are substances in which light and sound often travel through.


Empty space.Empty space.Empty space.Empty space.


Sound can't really travel through light.


Sound waves need a medium to travel through - the medium may be solid, liquid, or gaseous. Electromagnetic waves (including light) can also travel through empty space.


Electromagnetic waves can travel though empty space. Sound waves can travel through matter.


Light waves and electromagnetic waves can travel through empty space. Water waves can only travel through matter. Hope this helped!


Because sound is made from vibrations and vibrations cant travle through empty space


sound and light can travel through sound air solids water liquids light wiers lightbubs extentions etc.



The light waves they reflect travel through empty space but sound waves do not.


There is lots of energy involved near some black holes, but sound doesn't travel through empty space.There is lots of energy involved near some black holes, but sound doesn't travel through empty space.There is lots of energy involved near some black holes, but sound doesn't travel through empty space.There is lots of energy involved near some black holes, but sound doesn't travel through empty space.


light can but sound cant as there is no air


No, it does not. It can travel through any open space. Sound, unlike light, needs a medium to travel. So light can travel through outer space but sound cannot because there is no medium.


They travel in waves through matter.


Sound waves need a medium (substance) to travel through. Air, water, and metal can all act as mediums for sound waves. The molecules of the substance are slightly disturbed from there equilibrium position as the sound wave passes by. Empty space does not have any atoms or molecules, so sound waves are not able to travel through empty space.


Radio waves travel through empty space because they are electromagnetic waves, whereas sound is a wave that must travel through air.


Sound and Light can travel through space.


Light is electromagnetic radiation, while sound is the vibration of air. While sound travels at around 1,100 feet per second, light travels at a speed of 186,000 miles per hour. Also, sound requires a solid, liquid or gas to travel while light can travel through empty space.


No. Light can't travel through solid brick, steel etc, but sound can.


Sound Waves and Light Waves are different. The following are the differences I am aware of:Velocity: Light Waves travel through air and empty space at a speed of approximately 186,000 miles per second or 300,000 kilometers per second. Sound waves travel through air at the speed of approximately 1,100 feet per second or 330 meters per second.Wave Type: Sound Waves are longitudinal in nature whereas Light waves are transverse in nature.Light Waves can travel through vacuum whereas Sound cannot.Hope this helps.
